Nathan Myhrvold, Microsofts former chief technology officer, thinks so. His company, Intellectual Ventures, has assembled commonly available technology parts used in printers, digital cameras and projectors to make rapid lasers to shoot down mosquitoes in mid-flight. If bed nets are the low-tech solution to combat the deadly disease caused by a parasite transmitted when certain mosquitoes bite people the laser is a high-tech one.
He gave the first public demonstration of the laser, which was cobbled together from parts found on eBay, at the annual TED conference in Long Beach, Calif., which features lectures and demonstrations by experts in a wide range of fields, including technology, politics and entertainment.
After hundreds of mosquitoes (which were kept in the hotel bathroom until showtime) were released into a glass tank, a laser tracked their movements and slowly shot them down, leaving their carcasses scattered on the bottom of the tank. While the demonstration was slowed down for public viewing, Mr. Myhrvold said that normally the lasers could shoot down anywhere between 50 to 100 mosquitoes per second.
Mr. Myhrvold played a slow-motion recorded video that showed what happened to a representative mosquito. As the insect flew, a sudden light beam struck it, disintegrating parts of its body into a plume of smoke. It fell, even as its wings continued to beat.
Mr. Myhrvold said the software detects the speed and size of the image before deciding whether to shoot. It would reject a butterfly or a human, for example, and more powerful laser blasts could be used for locusts. In regions afflicted by malaria, the lasers could be used to create protective fences around clinics, homes, or even agricultural fields as a substitute for pesticides.
